SPINNING-SPINDLE.

Specification of Letters Patent.

Patented Sept. 24, 1912.

Application filed July 5, 1912. Serial No. 707,733.

To all whom it may concern:

Be it known that I, ALBERT H. MORTON, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Spinning-Spindles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an improvement in spinning spindles. Its object is to reorganize and improve the construction of the devices for connecting or securing the bobbin to the spindle so as to rotate with it, and to this end the invention consists in the spindle hereinafter described and particularly defined in the claims.

In the accompanying drawing illustrating the preferred form of the invention, Figure 1 is an elevation of the spindle with the lower end of the bobbin shown in section; Fig. 2 is a sectional elevation; and Fig. 3 a crosssection taken on the line 33 of Fig. 2. v

The spindle blade 1 supports the whirl 2 which is of the sleeve type having a base or holding portion 3 fitting the spindle tightly and holding the whirl in position thereon. The whirl is provided with a bobbin support 4 upon which the bottom of bobbin 5 rests when it is in position on the spindle, as seen in Fig. 1. The bobbin clutch is integral with the whirl and consists of four arms 6 projecting upwardly from the whirl, being resiliently or yieldingly connected thereto by the long, thin reduced portions 7. The clutch is made by necking down the upwardly projecting cylindrical portion from which the arms 6 are formed and by cutting the slots 9 in the cylindrical portion to form the arms therefrom. This cylindrical portion is bored at 8 to adiameter slightly larger than the diameter of the spindle and its exterior diameter is greater, ordinarily, than the hole in the bobbin adapted to receive it, so, when the bobbin is put on the spindle, the arms yield or give so as to enter the opening in the bobbin. This combined whirl and clutch is, it will be observed, of the simplest form and made of only one piece of metal. The machining operations required to be performed in producing it are, obviously, simple and inexpensive. The upper ends of the clutch members 6 are sufficiently rigid for all the ordinary purposes of use to which the device is subjected to stand any strains or blows to which they may be subjected without injury or permanent distortion of their shape, and at the same time are sufiiciently flexible to fit bobbins having openings of varying sizes and to engage them with good driving hold. The arms, being integral with the whirl, are accurately positioned with relation to the blade, the whirl and the bobbin support. Again, the upper ends of the clutch arms 6 being entirely free, a considerable capacity of movement is afforded the arms without making the reduced portions 7 so thin as to render them weak or liable to be permanently distorted or broken. The structure therefore presents a strong connector which will stand long legitimate use and considerable abuse without disabling injury.

The present invention is not limited to the illustrated embodiment as it may be embodied in other forms within the scope of the claims. The use of the sleeve type of whirl is not essential, nor the position of the bobbin support with relation to the whirl; neither is the location of the base or holding portion of the essence of the invention, but viewed in its broader aspects the invention contemplates an integral whirl and bobbin clutch characterized by the 11 wardly projected free-ended resilient bobbin clutching members united to the whirl at their lower ends, and being stifi' enough to stand ordinary knocks and blows and resilient enough to hold the bobbin securely to the spindle. Other features of the invention are set forth in the claims.

Having thus described the invention, what is claimed is:

1. A spinning spindle having, in combination, a spindle-blade, and an integral whirl and bobbin-clutch secured to the blade, said clutch consisting of a plurality of upwardly-projected free-ended resilient bobbin-clutching members united to the whirl at their lower ends, substantially as described.

2. A spinning spindle having, in combination, a spindle-blade, an integral whirl and bobbin-clutch consisting of a whirl, a base supporting the Whirl, and a plurality of plurality of clutch-arms resiliently conclutch-members projected upward from the nected to the base, substantially as de- 10 base, substantially as described. b scribed.

8. A spinnin spindle having, in com ination, a spindleblade and acombined Whirl ALBERT MORTON and clutch consisting of a single integral, Witnesses: member having a base secured to the spindle- GEORGE E. S'rEBBINs, blade, a Whirl supported therefrom, and a: ANNIE C. RICHARDSON.
